Brent reservoir is a designated Site of Special Scientific Interest. On a summer’s day dragonflies hum and butterflies flutter across a large expanse of reedbed supporting several orchids including the southern marsh, common spotted, pyramidal and bee. Crisp winter mornings bring fantastic views of feeding duck and wildfowl. Amongst the reed and sedge warblers watch out for the kingfisher, heron, tawny owl, black cap and chiff chaff.

Covering over 51 hectares the site has an underground bat hibernation site where pipestrelle and noctule bats have been recorded.

Originally the lake was formed by the confluence of two brooks that were dammed in the mid 1830s to supply the Grand Union Canal with water. The reservoir was enlarged in 1851 and the area became a fashionable centre for angling and birdwatching.
